Rejuvenation of woman’s skin could tackle diseases of ageing

Rejuvenation of woman’s skin could tackle diseases of ageing

Science
Fátima SantosResearchers have rejuvenated a 53-year-old woman's skin cells so they are the equivalent of a 23-year-old's.The scientists in Cambridge believe that they can do the same thing with other tissues in the body.The eventual aim is to develop treatments for age-related diseases such as diabetes, heart disease and neurological disorders.The technology is built on the techniques used to create Dolly the cloned sheep more than 25 years ago.The head of the team, Prof Wolf Reik, of the Babraham Institute in Cambridge, told BBC News that he hoped that the technique could eventually be used to keep people healthier for longer as they grow older."We have been dreaming about this kind of thing. Many common diseases get worse with age and to think about helping people in this way is super ex...
Slow walking at 45 ‘a sign of faster ageing’

Slow walking at 45 ‘a sign of faster ageing’

Health
How fast people walk in their 40s is a sign of how much their brains, as well as their bodies, are ageing, scientists have suggested.Using a simple test of gait speed, researchers were able to measure the ageing process.Not only were slower walkers' bodies ageing more quickly - their faces looked older and they had smaller brains.The international team said the findings were an "amazing surprise".Doctors often measure gait speed to gauge overall health, particularly in the over-65s, because it is a good indicator of muscle strength, lung function, balance, spine strength and eyesight.Slower walking speeds in old age have also been linked to a higher risk of dementia and decline.'Problem sign'In this study, of 1,000 people in New ...
Ear ‘tickling’ therapy could ‘help thwart ageing’

Ear ‘tickling’ therapy could ‘help thwart ageing’

Health
Tickling the ear with a small electric current could rebalance the nervous system in over-55s and help them age more healthily, research suggests.Stimulation of the vagus nerve, which connects to the heart, lungs and gut, led to improvements in body, sleep and mood, a small study found.The University of Leeds team said the procedure could make a big difference to people's lives.But more research is needed to work out the long-term health effects.Why the ear?The ear acts as a gateway to the body's nervous system.One small branch of the vagus nerve can be stimulated via the skin in specific bits of the outer ear.To some people, the therapy feels ticklish. To others, it's painless.What's the vagus nerve?Also called the "wandering ne...
Apple's iPhones slowed to tackle ageing batteries

Apple's iPhones slowed to tackle ageing batteries

Technology
Apple has confirmed the suspicions of many iPhone owners by revealing it does deliberately slow down some models of the iPhone as they age.Many customers have long suspected that Apple slows down older iPhones to encourage people to upgrade.The company has now said it does slow down some models as they age, but only because the phones' battery performance diminishes over time.Apple said it wanted to "prolong the life" of customers' devices.The practice was confirmed after a customer shared performance tests on Reddit, suggesting their iPhone 6S had slowed down considerably as it had aged but had suddenly sped up again after the battery had been replaced."I used my brother's iPhone 6 Plus, and his was faster than mine? This is when I knew something was wrong," wrote TeckFire.Technology webs...
